图1 131I相关唾液腺炎的造影图像Figure 1 Sialogram of radioactive iodine-induced sialadenitis A 48-year-old female patient with recurrent swelling of bilateral parotid and submandibular glands for a period of 8 months. These symptoms occurred one year after surgery for thyroid cancer and radioactive iodine therapy. Sialogram of the right parotid gland showed stenosis of distal duct (black arrow), ectasia of hilum duct (blue arrow) and atresia of intraglandular duct (red arrow). |
图2 过敏相关唾液腺炎的造影图像Figure 2 Sialogram of allergy-related sialodochitis A 29-year-old female with comorbid allergic rhinitis complained of recurrent swelling and mucus plug exudation of four major salivary glands for 3 years. Laboratory tests showed an elevated level of immunoglobulin E (128.9 IU/mL; Normal range: ≤100 IU/mL). Sialogram of the right parotid gland showed ectasia of the main duct and "snowflake" appea-rance of the branch ducts (black arrow). |
图3 成人复发性腮腺炎的造影图像Figure 3 Sialogram of adult chronic recurrent parotitis A 24-year-old male patient with recurrent swelling and pain of the left parotid gland for half a year. He complained of a history of "parotitis" 10 years ago. Sialography showed "punctate and globular" ectasia of the terminal ducts of the left parotid gland. |
图4 腮腺良性肥大伴管炎的造影及CT图像Figure 4 Sialogram and CT images of sialadenosis with sialodochitis A 45-year-old male with long-term drinking and smoking habits complained of persistent swelling of bilateral parotid glands for 7-8 years. A, enlarged bilateral parotid glands on the axial CT image; B, stenosis (red arrow) and ectasia (black arrow) of the main duct, and clustered branch ducts on the sialogram of the right parotid gland; C, persistent contrast media on the functional film. |
图5 原发性导管狭窄性唾液腺炎的造影图像Figure 5 Sialogram of idiopathic sialadenitis A 72-year-old female with a 3-month history of recurrent swelling of the right parotid gland. A, sausage-like appearance of the main duct of the right parotid gland; B, persistent contrast media on the functional film. |
